WILLIAM E. MOREY, OF CHICAGO, ILLINOIS, ASSIGNOR TO NATIONAL DUMP CAB COMPANY, A CORPORATION OF MAINE.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed June 25, 1914. Serial No. 847,235.

To all whom it may concern:

Be it known that I, WILLIAM E. 4MOREY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Actuating Mechanism, of which the following is a specification.

This invention relates to improvements in door actuating mechanism, and has for its object to provide a new and improved mechanism of that character in combination with cars having dump doors.

The principal object of my invention is to provide a new and improved means for op erating the dump doors and means for looking and supporting such doors when in closed position.

Still another object is to provide means'in conjunction with the above, for locking the supporting members in supporting position.

Still another object consists in the provision of a new and improved structure to affect the above and other objects.

My invention is set forth and described in .the following specifiaction and accompanying drawings, in which:

Figure 1 is a side elevation of a portion of a car showing my invention appliedthereto; Fig. 2 is a vertical transverse section of the same; Fig. 3 is a detail side elevation of the operating mechanism; Fig. 4is a detail plan view, partially in section, with the supporting and locking shaft; Fig. 5 is a vertical transverse section showing a detail of my invention; Fig. 6 is a view similar to Fig. 5 on another plane.

Like numerals refer to like elements throughout the drawings, in which 10 indicates generally a car having the side walls 11 supported by and attached to the stakes 12. Extending downwardly from the lower portion of the walls 11 to the floor of the car, and inclined with respect thereto, are the deflecting walls 12. The car is further provided with the doors 13 at the bottom thereof, these doors being hinged at 13 for opening or closing thereof. Each of the doors 13 is provided with the attached 2- bars 13 on the bottom thereof adj acent the side edges. An angle bar 13 is attached to the front and bottom of each of these doors 13 and to a flange of this angle 13 is attached the end link of a chain or other flexi ble member 14 and at their other ends these I vided with their chains 14 are attached to an operating shaft 15 which is journaled in the upwardly extending plates 16 which have base flanges 16' riveted or otherwise attached to the under side of the deflecting walls 12. At. its ends the shaft 15 is provided with a ratchet or star wheel 18 attached thereto. This wheel ,18 is provided with the hub portion 18 upon which is 'rotatably mounted a collar 19 formed integrally with an outwardly extending socket 19 in which may be fitted an operating lever or the like. A washer or flange 20 may be provided adjacent the hub 18 to prevent accidental displacement of the collar 19, the said flange 20 being preferably held in place by a cotter pin 20*, or the like. Mounted on the shaft 15 adjacent the ratchet or star wheel 18, is a second ratchet or star wheel 21 which coacts with a pawl or detent 22 pivotally mounted upon the pin 22 carried by the adjacent brackets .16. This pawl 22 is so arranged as to permit its engagement with the star wheel 21 to prevent unwinding of the shaft 15 while permitting winding thereof, as will be apparent to those skilled in the art. A dog or pawl 19 is pivotally mounted on a pin 19 carried by socket 19 and is so arranged as to permit its movement into engagement with wheel 18 in such wise that when a handle inserted in socket 19 is oscillated forward and back, the said pawl 19 will slip over the ratchet 18 when moving in one direction and will engage the same on its reverse movement to rotate the shaft 15, the pawl 22 preventing a return or reverse movement of the shaft 15 during such winding thereof. Through this mechanism I am enabled to rotate the shaft 15 in the proper direction to wind the chain 1 1 thereon to affect a closing or partial closing movement of the doors 13.

Partition webs oricross plates 25 extend transversely of the car 10 below the floor thereof and are located between and at the ends of the doors 13, as shown in Figs. 1 and 2 for example. These plates 25 are provided near their outer ends with slots 25 extending from adjacent such outer ends upwardly and inwardly of the said plates or webs 25, as is clearly shown in Fig. 2, for example. These slots are proinner ends approxi mately horizontal or slightly downwardly turned as indicated at numeral 25 s;

Figs. 2 and 6, for a purpose to be hereinafter described. Extending through these slots and mounted for movement therein are the shafts 30 substantially parallel with and located near the shafts 15. Chains or flexible members 31 extend approximately at right angles to the axis of the shaft 30 and are looped one or more times around said shaft, the ends being secured to eye bolts 32, 33 carried by the car structure. If necessary in some instances I may attach the chains at a proper point to the shaft to prevent relative slipping. At their ends the shafts 30 are provided with the collars 34 secured thereto and each provided with a star or ratchet wheel. 35. Mounted upon this collar or hub 3st is a ring or collar 36 similar to number 19, and similarly carrying a socket 35 in which may be inserted a lever or operating handle. A pawl 37 is pivotally attached to a pin 3T carried by socket 36, see Fig. 3, and is intended to coact with star or ratchet wheel 35 in a manner similar to that explained and described in connection with ratchet 18, the purpose being to enable rotation of shaft 30 to be affected by oscillation of socket 36 Rotation in the proper direction of shaft 30 will result through the medium of chains 31 in bodily movement or rolling of the said shaft from one extreme of the slots 25 to the other thereof, as is clearly illustrated in Fig. 2. On the left side the shaft 30 is shownat one limit of its travel, while on the right hand side it is shown at the other limit of travel.

The purpose of this structure is to effect the absolute closing and supporting of the doors 13, the operation being as follows When the shaft 15 has been rotated to almost close the doors 13, the same may be held in partially closed position by-means of a pawl 22 and ratchet 91, described above, while the shaft 30 is bodily moved from the position shown at the left hand side of Fig. 2 to that shown in Fig. 6, during which movement the said shaft will contact with the lower surface of Z-bars 13 and through the inclination of the slots 25 the shaft 30 will force .the doors 13 to closed position as illustrated at the right hand side of Fig. 2. Owing to the provision of the horizontal or slightly down-turned portion 25 of slots25 the shafts 30 will be held against accidental dis placement such as would permit the sudden opening of the doors 13 and throw the entire weight thereof on chains 14. Shafts 30 are even more firmly held in position, supporting and locking the doors 13 when the car is loaded and the weight of such load is resting on said shafts 30. This construction is further advantageous in that it transmits and distributes the load in the car to and throughout the car under-frame, as will be apparent. To further guard against accidental movement of the shaft 30 from supporting position, I provide the additional locking means shown in Fig. 5 and comprising the stop arm 10 pivotally mounted at 40 adjacent one extremity to a portion of the adjacent web or plate 25. This stop arm is provided with a concaved end 10 adapted to closely fit and contact with a portion of collar 34: and by its location it is apparent that when the stop arm 40 is in the position shown in Fig. 5, it will directly resist return movement of the shaft 30 from supporting position. To retain this stop arm 10 in its locking position, shown in Fig. 5, I provide the locking cam e1 pivotally mounted at 41. This cam is so arranged that it may be swung into the position shown in Fig. 5 directly beneath and contacting with the under-side of stop arm 10 thereby forcing it tightly against the shaft 30 and retaining it in such position. This cam 41 is provided with the engageable portion 11" which may be utilized in moving it from or to locking position. A strip 12 extends between the pivotal points 410 411 and serves to hold stop arm 40 and cam 11 against lateral movement.

It is believed that the description above is sufficient to render the construction and operation of the device clear to those skilled in the art. I would. state further, however, that in releasing or opening the doors to permit discharge of a load. the following operation is performed: The pawl 22 is thrown to unlocking position, thereby permitting release of the door closing shaft 15. The locking cam-11 is then thrown out of locking position, permitting the drop arm 40 to drop or be forced to released position, whereupon the shaft will move or may be moved by means of socket 36 and pawl 37 from beneath the doors permitting the same to drop and discharge said load.

lVhile I have shown and described my device with more or less particularity, I do not wish to be restricted thereto beyond the scope of the appended claims.
